The Embedded I/O Company TPMC917 4 Channel Serial Interface RS232 with 4 Mbyte NV-SRAM
Application Information Technical Information
The TPMC917 is a standard single-width 32 bit PMC
Standard single-width 32 bit PMC module conforming
module providing 4 Mbyte SRAM with battery backup by an
on board lithium cell for all SRAM devises, and four ESD
protected RS232 channels (TPMC917-10 only).
The 4 Mbyte NV-SRAM is organized in two banks, each of
4 Mbyte NV-SRAM with battery backup by on board
them provides 512k x 32 bit memory. During normal
operation (standard 5V supply applied to the SRAM’s) the
Battery capacity is monitored every 24 hours
capacity of the lithium cell is monitored every 24 hours by
Interrupt can be generated to control battery
the battery monitor device and an interrupt can be
generated if the battery voltage is too low. The monitor
4 channel serial RS232 interface, ESD protected
device switches the power supply of the SRAM’s from the
standard 5V to the battery if the 5V supply drops below the
64 byte transmit FIFO per channel, 64 byte receive
threshold level of the battery monitor device. Any active
access to the SRAM’s at this point is executed correctly
Programmable baud rates up to 115.2 Kbaud
within 1.5µs. After this time any further accesses to the
SRAM’s are not possible. A miniature DIP switch allows the selection of the battery backup source either from the on board lithium cell or from an external battery via the P14 I/O connector. The TPMC917-10 provides four RS232 channels. Each channel has a programmable baud rate up to 115.2 Kbaud. The 4 channel UART16C654 provides 64 byte transmit FIFO and 64 byte receive FIFO for each channel to significantly reduce the overhead required to provide data to and get data from the transmitter and receiver. The FIFO trigger levels are programmable. The channels are ESD protected up to +/-15kV according to the human body model
